DRIP-VALVE.

Application filed August 19, 1915.

To all whom it may concern:

Be it known that I, CHRISTOPHER J. SMITH, a citizen of the United Statesof America, residing at Jersey City, in the county of Hudson and Stateof New Jersey, have invented certain new and useful Improvements inDrip-Valves, of which the following is a specification.

The present invention relates to improvements in drip valves, and isdesigned especially for the purpose of providing a device through whichliquids, as oil, may slowly but continuously pass to be used for variouspurposes.

The primary object of the invention is the provision of a device of thischaracter which is comparatively inexpensive in cost of production,economical, but durable and ellicient in its operation and theperformance of its functions.

The invention consists essentially in certain novel combinations andarrangements of parts of the drip valve as will be hereinafter morefully pointed out and claimed.

In the accompanying drawings 1 have illustrated one complete example ofthe physical embodiment of my invention constructed according to thebest mode I have so far devised for the practical application of theprinciples of my invention, and one which has proven highly satisfactoryin actual use.

Figure 1 is a sectional view of the casing, showing the plug in full.Fig. 2 is a partial sectional view of the plug of thecock. Fig. 3 is aview in elevation of the plug as seen from the left in Fig. 1 and 2.

In the preferred embodiment of my invention ll employ a standard brasscasing as 1 having the usual tapered bore 2 for the valve plug, and theproximal threaded end 3 or inlet and distal end or outlet 4. A recess 5is provided in the front wall of the bore of the casing whichcommunicates with the outlet or mouth 1 and extends vertically upwardtherefrom to near the top of the tapered bore.

The plug 6 of the cock or valve is tapered as usual to fit its bore 2and it may be turned in its bore by the handle 7, to open or closecommunication through the valve or cook. At 8 the plug is boredhorizontally and a Specification of Letters Patent.

Serial No. 116,317.

well or hollow space 9 is centrally located in the plug beneath theopening or port 8, and the port 8 registers with the inlet opening 3 ofthe casing when the valve plug is turned to proper position as in Fig.1.

The usual screw 10 and washer 11 are employed to secure the plug in itsbore, and at 12 a groove is indicated in the periphery of the plug whichextends half way around the plug from the opening or port 8 to a pointdiametrically opposite thereto where it opens into or communicates withthe recess or groove 5 in the wall of the tapered bore of the casingwhen the plug is in open position. When the valve plug is closed it isturned through an arc of 1-5 as usual until ablank closes the inner endsof the inlet and outlet openings 3 and 4, with the port 8 against theblank face of the tapered bore.

In Fig. 1 the cock is open to permit passage therethrough of oil orother liquid, the oil passing from the inlet opening 3 into the well andport, which are first filled, and then passing upwardly through thegroove 12 half around the plug, through the groove 5 and thence outthrough outlet 4.

During the passage of the oil, it will be noted that heavy or extraneousmatters or sediment are provided for by the use of the well, for herethe sediment is lodged, the heavier portions naturally gravitating intothe well while the lighter matter passes up through the groove 12 andaround the plug as described. he well may be cleaned out when necessary,and the plug replaced for further use. In this manner a continuouspassage of oil is attained, through the drip cock and the oil drips fromthe outlet t for the purposes desired.

What I claimis:

The combination in a drip cock with its casing, and a plug having achamber therein, said casing having a recess in its wall communicatingwith its outlet, and said plug having a port communicating with thechamber and adapted to register with the inlet of the casing and anexternal groove extending from said port adapted to communicate with therecess in the casing.

Tn testimony whereof I affix my signature.

CHRISTOPHER J. SMITH.
